sketchy

Etymology

It is formed from English sketch + -y.^[2][3][4][5] Sketch, first recorded in the 1660s, is from Dutch schets or German Skizze, both from Italian schizzo.^[3][2]

Earliest recorded meaning

Giving only a slight or rough outline, without details; at first of writings and authors: 1805, in the Edinburgh Review.^[2][3][6]

Semantic evolution

From 1811 the word was used of a style in writing or painting, and of a picture made of outline without much detail.^[2][3] In 1878 it took on the colloquial sense of flimsy, unsubstantial or imperfect, perhaps through the idea of something unfinished.^[3][2] In American slang, from 1915 it could mean brief or minimal,^[7] and in American campus slang of the late 1980s and 1990s it meant unstable or strange, untrustworthy or suspicious, and second-rate.^[7] The OED dates the sense "dangerous, disreputable or untrustworthy" to 1982, in an Indiana newspaper,^[2] and Collins labels it chiefly American slang.^[8]
